Hi, Growing hyacinth bulbs in vases ie without soil was discussed at a talk at my local centre a few weeks ago and I've hence just "planted" 3. I spotted in this months magazine that is says to grow in the dark for first 10-12 weeks and that afterwards the bulb is spent. I don't think that chap at the garden centre mentioned putting in the dark (I might have missed that bit!) so they are on my windowsill and he definitely said that the bulb could be planted in the garden afterwards. How important is the dark? They are already growing roots. And do you reckon the bulbs might be reusable outside next year? Thanks Noodle
